Security and Identity: More Security Measures, More Encryption Coverage, Easier Switching
Between Orgs

We’ve improved two-factor authentication management, provided more
security measures around identity verification, and now require the HTTPS protocol to
log in. Encryption now supports Lightning Experience, protects more fields, and
secures data in even more apps. Also, your users can easily switch between orgs with the
user switcher.

Authentication and Identity
You can rescue your users during two-factor authentication emergencies by giving them a temporary verification code. In Lightning Experience, a user with multiple usernames on the same Salesforce org or different orgs can easily switch between them with the user switcher.

Shield Platform Encryption
Your users now get all the benefits of Shield Platform Encryption in Lightning Experience, in Salesforce Classic, and on your mobile device with Salesforce1. Even more of your go-to apps support encrypted data, and you can encrypt custom fields in managed packages.
